SEWING-MACHINE,

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed January 22, 1914. Serial No. 813,626.

To all whom it may concern l Be it known that I, JACOB DAsnEw, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification.` y n This invention relates to improvements 1n sewing machines, and especially to that class in which the needle has a longitudinal, as well as a vertical, reciprocal motion, for the purpose of forming a staggering, Zig-zag, or other fanciful stitch.

The object range the parts that the done in close places, such as sewing bels on the inside of pockets, etc.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification and pointed out in detail in the appended claims.

ln the accompanying drawings, Figure 1 is a side elevation of my invention, partly in section. Fig. 2 is a front end view of Fig. 1. Fig. 3 is an enlarged side elevation of the horn, the outer end of which is in section and showing the looper and the parts for operating same. Fig. 4 is an end view of Fig. 3, the cap on the end of the horn being removed. Fig. 5 is a detail plan View of the looper. Fig. 6 is a plan view of the feed-foot.

Referring to the accompanying drawings, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the base of the machine which is provided with a longitudinal horn 2 and a vertical upright portion 3 having an arm 4 provided on its outer end with a head 5. The main shaft 6 has a pulley 7 on its outer end, to which power is transmitted from any suitable source. This main shaft 6 projects through the arm 4 and has a disk 8 on its inner end to which is pivoted one end of the rod 9 the other end of which latter is pivoted to the collar 10. The said collar 10 being fast on the needle bar 11 the latter, and consequently the needle, will be reciprocated vertically as the disk 8 is revolved with the main shaft 6. In the side of the arm 4 is mounted a disk 12 having a camslot 13 in the face thereof and a gear-wheel on the inner end in mesh with the gearwheel 14 which latter is fast on the main of the invention is to so arstitching may be the lashaft 6. The grooved lever 15 is pivoted at 16 to the arm 4 and has a .roller 17 projecting therefrom which fits into the cam slot 13. The rod 18 has one end adjustably connected to the lever 15and the other end connected to the frame 19 in the head 5. This frame 19 is pivoted at 20, 20 to the head 5. The revolution of the cam-disk 12 causes the lever 15 to rock on its pivot 16 imparting a longitudinal reciprocal motion through the rod 18 tothe frame 19, through which latter the needle bar 11 projects, thus also imparting a longitudinal reciprocal motion to the needle bar and consequently to the needle. It will thus be seen that the needle has both a longitudinal and a vertical reciprocal motion, whereby a staggered or zig-zag stitch is formed. The main shaft G is also provided with a pulley 21 from which power is transmitted through the belt 22 to the pulley 23 on the shaft 24. This shaft 24 is provided with a gear-wheel 25 in mesh with the gear-wheel 2li, which latter has a beveled gear in mesh with the beveled gear-wheel 27, which in turn is in mesh with the beveled gear-wheel 28 on the back of the looper 29. It will thus be seen that the looper 29 is revolved by power transmitted thereto from the shaft 24 through the gear-wheels 25, 26 and 27. The feed foot 30 is at the upper end cf the frame 31 which latter is pivoted at 32 and has an elongated slot 33 to permit of its vertical movement. The said frame 31, and consequently the foot 30, is reciprocated vertically by means of the cam 34 on the shaft 24. This cam 34 fits be tween the lower end of the frame 31 and the projecting arm 35 and as the shaft 24 revolves the said cam raises and lowers said frame 31 and the feed-foot 30. The frame 31 and feed foot 30 are reciprocated longitudinally by the rocking of the shaft 36, which latter is provided with and has a bifurcated lever 37 in the outer end of which is pivotally mounted the outer end of the arm 35.

It will be seen that by having the shuttle and feed operated in the longitudinal horn, a coat, or other garment, may be slipped over said horn in such a manner as to allow the operator to sew in close places, such as coat pockets, where it is impossible to operate the usual flat base machines.

Having thus described my invention, what I claim is:

l. In a sewing machine, the combination of a base having a vertical upright portion, a longitudinal Work-supporting horn 2 projeeting from one side of said base, an arm 4 projecting from said Vertical upright portion and extending over said horn, a main shaft 6 mounted in said arm, a needle bar mounted in the outer end of said arm 4 and operated by said main shaft, a shaft 24 mounted in said horn, a belt 22 connecting Said main shaft G with the shaft 24, a gear Wheel 25 mounted on the shaft 24, a gear Wheel 26 in mesh with the gear Wheel 25, a gear Wheel 27 in mesh, with the gear Wheel 26, a looper 29, a beveled gear Wheel 28 on the back of said looper in mesh with the gear Wheel 27, a feed foot 30, and means for operating said feed foot.

2; In a sewing machine, the Combination of a base having a vertical upright portion, a longitudinal Work supporting horn 2 projecting from one side of said base, an arm 4 projecting from said Vertical upright portion and extending over said horn, a main shaft 6 mounted 1n said arm, a needle bar mounted in the outer end of said arm 4 and operated by said main shaft, a shaft 2K4 mounted in said horn, a belt 22 connecting said main shaft 6 with the shaft 24, .a gear Wheel 25 mounted on the shaft 24, a gear Wheell 26 in mesh with the gear Wheel 25, a gear Wheel 27 in mesh with the gear Wheel 26, a looper 29, a beveled gear Wheel 28- on'the back ofl said loop'er in Vineshwith the lgea-r Wheel 27, a frame 31 having a feedfoot' at its upper end and an arm 35 projecting thereirom, abifureated lever 37 connected to the arm 35, and meanslfor rockingsaid arm37. i y

In testimony whereof I aiX my signature in presence `of tWo Witnesses `i JACOB DASHEW. Witnesses:
